Commissioning Data Sets (CDS) Introduction

The Commissioning Data Sets (CDS) are maintained and developed by the NHS Digital, in accordance with the needs of the NHS and the Department of Health and Social Care.

Commissioning Data Sets form the basis of data on ACTIVITY carried out by Organisations reported centrally for monitoring and payment purposes. They support the current Healthcare Resource Group (HRG) version for calculation of payment to trusts and monitoring of other initiatives.
